ZIP archive, 1.09 GB, with scatter firmware for model A013F, binary revision U7, Android 10 (OS10), packaged for dead boot repair. No full build string is given in the name, so check the contents for the exact version. The scatter file inside lets MediaTek flashing software such as SP Flash Tool write each partition directly, which is the usual way to recover a phone that no longer powers into any mode. Make sure the device is a U7 binary or lower, and back up NVRAM to keep IMEI and RF calibration.
